Vehicle Output Displays for Dynamic Transport Error Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle marking techniques are prone to obscurity due to environmental factors and can mar the vehicle, while digital identification methods require additional equipment and can be ineffective in crowded environments.
Innovation Solution
Utilizing native vehicle systems such as color-changeable internal LED lighting and information displays to provide dynamic notifications of vehicle states, including transportation errors and handling issues, thereby eliminating the need for physical markings and additional scanning equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If physical markings are written directly onto the vehicle, then identification information can be conveyed, but the markings can become obscured due to environmental effects and can mar the vehicle
Solution Approach 1:
The patent replaces physical mechanical markings with electronic display systems. Vehicles equipped with displays can dynamically show identification information, routing instructions, and status updates without any physical contact with the vehicle surface, eliminating both obscuration and marring issues
Solution Approach 2:
The patent utilizes changeable display parameters (content, color, brightness) to convey different vehicle information states. The display can dynamically update information without physical alteration, allowing the same physical medium to convey varying information as needed
2Loss of information
If digital identification methods are used through broadcast signals and handheld devices, then vehicle identification can be achieved, but additional equipment and processing entities are required which adds expense and requires training
Solution Approach 1:
The vehicle's own display system serves as the identification and information conveyance mechanism. The vehicle self-presents its information through onboard displays, eliminating the need for external handheld devices or complex processing entities to read markings or broadcast signals
Solution Approach 2:
The vehicle display system performs multiple functions: it provides identification information, routing instructions, status notifications, and error alerts. This multi-functional approach replaces the need for separate identification devices and processing systems
3Loss of information
If digital identification methods are used in crowded environments with hundreds of vehicles, then vehicle identification can be attempted, but conflicting broadcast signals make the method less effective
Solution Approach 1:
Instead of vehicles actively broadcasting signals that can conflict in crowded environments, the patent has vehicles passively display information on their own displays. This reverses the communication direction from active transmission to passive presentation, eliminating signal conflicts while maintaining identification reliability

AI summary
A system receives a vehicle transport instruction for transporting a vehicle. The system instructs display of an indicator related to the transport instruction, using a first vehicle output. Further, the system determines whether a vehicle is in a state designated for alert notification based on at least a transportation error detected by the vehicle and changes at least one of the first vehicle output or a second vehicle output to indicate the transportation error responsive to detection of the transportation error by the vehicle.
